When usi ng suction cleaning tools of the This invention relates to improvements in kind now in general use, it is sometimes 65 suction cleaning tools, and the same has for found difficult to dislodge or work up dirt its object to provide a tool by means of which has become caked or hardened in the which dirt, Waste or other matter may be eascorners and crevices of rooms or compartily worked up and loosened so as to permit ments by reason of the fact that the configof the same being easily drawn into the sucuration of the tool is such that the matter tion apparatus connected with said tool. to be removed from such places cannot be Further, the invention has for its object reached.

The ferrule 11 is provided with a To the attainment of the aforesaid obdownwardly extending arm 12 carrying a 105 jects and ends my invention consists in the scraper13 which is positioned below and novel details of construction, and in the comextends forwardly of the inlet opening at bination, connection and arrangement of the front end of the tool. parts hereinafter more fully described and The scraper 13, which is of a width subthen pointed out in the claims. stantially equal to the diameter of the inlet 11o opening of the tool, has a flat lower or bearmg surface 14 and a rearwardly and upwardly inclined front surface 15 forming with the lower surface 14 a knife-like scraping edge 16 at the front of the scraper 13.

In use, the rear end of the body 10 is connected in any suitable manner to the suction hose or flexible. member communicating with the suction apparatus.

In operation, the tool is held in the hands of the operator with the bearing surface of the scraper 13 engaging the surface to be cleaned. As the tool is advanced the knifelike scraping edge 16 of the scraper 13 will loosen, break up, and dislodge any dirt that may be upon the surface being cleaned, and as the dirt is thus loosened it will be drawn into the inlet opening at the forward end of the tool by suction in the usual manner.

The suction cleanin tool above described is particularly adapta ale to the cleaning of floors provided with grooves or channels such as are found in cars, for example, as the scraper 13 maybe readily inserted within the grooves orchannels, and as it travels along the same it will dislodge any dirt that may be therein, thus insuring the due breaking up before the removal thereof by the tool in the manner above described.

By constructing the tubular body 10 of non-conducting material the operator is fully protected against the effects of an electric current should the metallic ferrule 11 accidentally come into contact with any carrier of electric current which may be located within the car or compartment being cleaned.

While the tool is particularly suited for the cleaning of car floors and the like it is, of course, equally well suited for removing dirt from the corners and crevices of rooms or compartments, which dirt or other matter cannot be readily reached and removed by tools of the type now in use.

what I claim and desire to secure by Letters 7 Patent is 1- l. A suction cleaning tool provided with an inlet opening, a relatively-11arrow scraper, means for supporting said scraper in position closely below and in advance of said inlet opening, and in a plane forming an angle with the plane of said inlet opening, substantially as specified. I

2. A suction cleaning tool provided with an inlet opening, a member secured to said tool adjacent to said inlet opening, a relatively narrow scraper positioned closely below and in advance of said inlet opening, and in a plane forming a right angle with the plane thereof, and means for supporting said scraper upon said member and in spaced relation to the inlet opening of said tool, substantially as specified.

3. A suction tool comprising a tubular body provided with an inlet opening, an annular member embracing the end of said tubular body, a downwardly extending arm secured to said annular member, and a scraper at the lower end of said arm extending forwardly therefrom in advance of saicil inlet opening, substantially as specifie 1. A suction tool comprising a tubular body provided with an inlet opening at its forward end, the plane of said opening being at right angles to the axis of said tubular body, a downwardly extending arm secured to said body adjacent the forward end thereof, and ascraper at the lower end of said arm and extending forwardly therefrom in a plane forming a right angle with the plane of said inlet opening, substantially as specified.
